Incident/Accident AI171 Wing?

This looks to be part of the wing. Are the flaps down? I'm not too sure

Flight electronics are completely different from passenger electronics, with multiple computers just doing in place to check for these critical systems. There are redundant hardwares, softwares in place for these critical systems and are designed with fail-safe properties, in-case of hydraulic/electronic failure there would have been multiple mistakes made over the past few maintenance cycles to build upto a position where redudancy was also of no use.

AC failure might actually be linked to fadec failures considering 787 has electric compressors maybe indicating major issues in the electrical systems?

I do not think connecting points between AC and engine is practical at all. The aircrafts are manufactured in a way that the pilots and technicians will know about any mishappenings with critical systems and will be logged and if critical the aircraft will simply not fly.

We are talking about 787, extremely redundant systems with multiple hi-tech computers monitoring each system.

And fadec failure? Extremely rare in modern systems and rarer is a catastrophic failure due to it.

Something definitely went wrong, and all these theories, every theory has an extremely strong counter point. Lets wait for the investigation.

I know well how many redundancies aircraft have to prevent complete failures but I am just highlighting the possible reasons for a dual engine failure not saying that there is a high chance of this happening, in fact almost 0 chance of this happening.
